It has been widely reported that there is a clause in the player’s current contract meaning he can leave for €35m if an offer is made before 2015, with the current contract expiring in 2017.

Dortmund are said to be keen to tie Reus down to a long term deal which would also abolish the release clause meaning if a top European side were to come back with it bid, they could command a fee in the region of €70m.

Reus was unfortunate to miss the World Cup through injury following a very good season with Dortmund and coach Jurgen Klopp is believed to want to tie all of his prized assets into long term deals following the departure of Shinji Kagawa, Robert Lewandowski and Mario Gotze in recent seasons.

New United boss Louis Van Gaal is reported to be an admirer of Reus and would be interested in bringing the player to the club as part of the rebuilding programme at Old Trafford. It is believed Van Gaal is also interested in Dortmund’s central defender Mats Hummels.
